ALBERT BLANCHARD CARE, OF ATLANTA, GEORGIA, ASSIGNOR TO THE PROCTER AND GAMBLE COMPANY, OF CINCINNATI, OHIO, A CORPORATION OF OHIO.

COTTON-SEED DRIER.

To all whom it may concern Be it known that I, ALBER'r BLANCHARD CARR, a citizen of the United States, and a resident of the city of Atlanta, in the county of Fulton and State of Georgia, have invented certain new and useful Improvements in Cotton-Seed Drier-s, of which the following is a full, clear, and exact description, reference being had to-the accompanying drawings, forming part of this specification.

It has been found that in the art. of drying cotton-seed, the ordinary grain driers are ineiiicient. Among other things which render their use inefficient in such drying, IS the fact thatcotton-seed will arch and jam in the outlets of the ordinary drier. Moreover ordinary slides or conveyers for re moving seeds from the mouth of a drier, such are are commonly used for grain, would result in a worse jam than if the passage of the seedswas unmolested. A further necessary improvement is the fact that a constant movement of the seed through the racks must be maintained or jamming will occur in the racks. I

It is the object of my invention, therefore, to construct a drier, with racks or chutes, formed of opposingly inclined plates, in the outlets whereof means is provided for removing the seed without clogging or jamming, thereby also maintaining a regulated iiow of seed through the drier. This I accomplish by that certain construction and arrangement of parts to. be hereinafter specifically pointed out and claimed.

In the drawings, Figure 1 is a vertical section throughthe drier, with a portion in side elevation. Fig. 2 is an enlarged sectional view on the same line, showing the adjusting means for the lower swinging inclined plates and the feed rolls. Fig. 8 is a cross section of a portion of the drier, showing the feeding rolls. Fig. 4 is a horizontal section of the same.

The various devices employed by me to accomplish my purpose of providing an ellicient drier of cottonseed are not the only ones by which the same rgult can be obtained. means, my desire being to combine with'a drier a non-jammingdevice which will deliver the dried material at a speed or in amounts which we y be regulated to suit con- T hey are merely the preferred I Specification of Letters latent.

ditions. One is enabled by my invention to accomplish numerous new and useful results in drying. In the first place, cottonseed may be run through a vertical rack drier since means of removing it are supplied. Also, the removing means are located adjacent to swinging plates in the mouths of the racks, thereby avoiding clogging. Again, no seed will fall through the machine unless the rotary devices are operated. The racks may be filled and the delivery device worked at a speed which will cause a regular flow of seed in the racks,

which cannot be obtained without this regular flow, as only part of a full rack will slide out if artificial means are not provided, and finally the number of tons per hour in the racks and subject to drying may be readily regulated. Thus I provide a new combination of parts which have extremely useful and novel functions.

The vertical racks are formed (Fig.1) of a number of staggered series of mutually inclined plates 1, said inclination being toward the bottom of each plate. The ends of the plates are mounted in any desired way in upright end plates 2, or in the side walls 3 of the drier. It will be understood that the number of racks may be multiplied as desired, both lengthwise or crosswise of the machine. The back end plate 2 for one of the crosswise series is employed for the forward end plate of the next rack in the series. By this arrangement, a continuous passage is provided for the seed, said passage being opened at 4 at the top edge of each plate, for the passage of air. In the drawings no means of creating a current of air is shown, but it will be understood that, as is usual, there willbe a current of air maintained by means of fans in the chambers 5 between the racks, which said air will strike and circulate in and around the seed through the open Spaces 4 in the ra c'ks. Angular bottom pieces 6 are provided to close the racks an chambers from the outer air.

One of the inclined plates 7 at the bottom end of each rack, which forms a mouth together with its adjacent platefor the racks, is swung on a "rod 8 which runs crosswise of the drier; The outside arms 10 of these plates are provided with slidable weights 11 to maintain them normally in contact, with the rotarydelivery device to be hereinafter described. The weights 11 are provided with set screws 12 for adjustment on the arms.

In the preferred construction of swinging ing longitudinal'pockets or corrugations 17, are mounted so as to revolve in the mouths 9.

. of the racks constructed as above described.

The direction of revolution is against the swinging plate and the pockets 1'? in the rolls will carry down out of the racks a quantity of the seed. Beveled gears 18 are mounted on the shafts 21 of these rolls and are engaged by beveled pinions 19 mounted on a shaft 20 which is journaled along the side of the machine in such a position that these gears will mesh. Rotation in either direction may be accomplished by varying the positions of the pinions to right or left of the gears 18. The shafts 21 extend clear across the machine to accommodate as many chutes as may be used crosswise the drier.

The machine is shown as bolted or clamped on I-beams 22, and as having a large hopper 23 for the final discharge of .means whereby the'bottom plate on one side will swing outwardly to accommodate the action of the feed roller.

6. In a drier for cottonseed, a series of vertical racks formed of mutually inclined plates, and means located within each rack for ejecting therefrom a continuous flow of the material to be dried and means whereby one of the inclined plates will swing out- 1 wardly to accommodate the action .of the ejecting means.
